Below is a walkthrough for the Bunker laser activation. This particular laser is located in a greenhouse of sorts. Once inside, you’ll see an assortment of different color flowers and panels. Using the flowers and “cross pollination” as a clue solve the panels. Once you unlock the panels behind the glass, be sure to examine all of your surroundings to solve them.
